Analysis of intermittency and correlations in hadronic Z decays
Multidimensional study of local multiplicity fluctuations and genuine multiparticle correlations is carried out with multihadronic Z/sup 0/ decay events recorded by the OPAL detector during 1991 to 1995. Local fluctuations are investigated in terms of normalized factorial moments. The large data sam...

| description | Multidimensional study of local multiplicity fluctuations and genuine multiparticle correlations is carried out with multihadronic Z/sup 0/ decay events recorded by the OPAL detector during 1991 to 1995. Local fluctuations are investigated in terms of normalized factorial moments. The large data sample allows for the first time in e/sup +/e /sup -/ annihilations a study of the normalized factorial cumulants in order to search for the genuine multiparticle correlations. The results are compared with generated samples obtained from the JETSET 7.4 and HERWIG 5.9 Monte Carlo models and the influence of model implemented Bose-Einstein correlations is studied.
